Distribution Transformers provide the necessary power for systems and buildings on the last transformation step from the power station to the consumer. Accordingly, their operation must be reliable, efficient and at the same time silent.Please take a look at our new product:FITformer® REG - Regulated Distribution Transformer

Description

GEAFOL Products

GEAFOL References

GEAFOL Cast-Resin Transformers have been in successful service since 1965. Many licenses have been granted to major manufacturers throughout the world since then. Over 100,000 units have proven themselves in power distribution or converter operation all around the globe.

GEAFOL with On-Load Tap-Changers

The voltage-regulating Cast-Resin Transformers connected on the load side of the medium-voltage power supply system feed the plant-side distribution transformers. The on-load tap-changer controlled transformers used in these medium-voltage systems need to have appropriately high ratings.

Transformers for Static Converters

These are special liquid immersed or GEAFOL Cast-Resin Transformers that are designed for the special demands of static converter operation.

Rated power: up to over 40 MVARated voltage: up to 52 kV

Neutral Earthing Transformers

When a neutral earthing reactor or earth-fault neutralizer is required in a 3-phase system and no suitable neutral is available, a neutral earthing must be provided by using a neutral earthing transformer.Neutral earthing transformers are available for continuous operation or short-time operation. The zero impedance is normally low. They can be designed as liquid-filled or GEAFOL Cast-Restin Transformers

Rated power: all common power ratings available

HVDC-Project, Germany

This 40-MVA-GEAFOL-Transformer was built for an experimental test line for a high voltage direct current transmission system at Siemens in Erlangen by the Transformer Plant Kirchheim, Germany.

GEAFOL Transformer for polysilicon reactors, China

This GEAFOL-Static Converter Transformer with 4,770 kVA was built at the Transformer Plant in Kirchheim, Germany for a chinese customer. HV/LV: 10,0 kV//2,39 KV/1,10 kV/0,66 kV/0,44 kV/0,33 KV

GEAFOL Static Converter Transformer

Rated at 23 MVA it feeds a pump drive in the new Block A at Vattenfall Europe AG‘s Moorburg powerplant.
